Greenland has a long and checkered history of human settlement: several Paleo-Inuit cultures since approximately 2,500 BCE, descendants of Vikings between the 10th and 15th centuries, and early modern Danes since 1721. All left their traces on the landscape, for example in the form of ancient domestic rubbish heaps. Composed of waste like animal bones, excrement, mollusk shells and human artifacts, these middens are a precious resource for archaeologists.

Indian millets are a staple for the country's population of more than a billion. They are also gaining global popularity, with rising exports and a reputation as a climate-resilient crop. Now, new research shows that their nutritional value includes a rich diversity of lipids, including a previously undetected group that may offer potential health benefits. The research is published in the journal Food Chemistry.

Diabetes and dementia appear to be closely intertwined, with each condition potentially influencing the other. Problems with insulin and glucose can affect the brain’s energy supply, increase inflammation, and damage blood vessels linked to memory loss. Researchers are also finding that some popular diabetes medications may lower dementia risk. These discoveries are opening new possibilities for protecting brain health as people age.

There’s something poetic about a British motorcycle manufacturer founded at the turn of the 20th century – one whose first “motorcycle” was a literal bicycle powered by a Belgian Clement engine – staging a comeback with thoroughly modern motorcycles and all-new powertrains.Continue ReadingCategory: Motorcycles, TransportTags: Norton Motorcycle, British, Adventure Bikes, Touring, Yamaha, Suzuki, TVS Motor

Researchers have calculated light levels at the ground surface across Switzerland to within 10 meters, in both open and forested areas. The model even simulates the shadows cast by individual trees.

An international research team, which included University of Tartu visiting doctoral student Wen-Gang Zhang and Professor of Botany Meelis Pärtel, has found a new solution to one of ecology's long-standing controversies—Darwin's naturalization conundrum, which addresses the question of why some species successfully establish in a new habitat while others do not. The research is published in the journal Proceedings of the National Academy of Sciences.

Scientists who study plant physiology and evolution have a new tool in their toolkit: a machine learning algorithm that can scan digital plant specimen collections and quickly measure leaf size and thickness.

An interdisciplinary team of Rice University researchers has uncovered previously unknown relationships between bacteriophages—viruses that infect bacteria—and their bacterial hosts, offering a powerful new tool for next-generation microbiome engineering.

The sail-backed predator Dimetrodon is one of the most iconic animals of the early Permian—long before dinosaurs dominated Earth. Most known species of this early relative of mammals reached large body sizes, sometimes up to 3 meters (10 feet) in length and 250 kilograms (550 pounds). Yet some species remained surprisingly small. A new study by an international research team led by Dr. Aurore Canoville of the Friedenstein Stiftung Gotha and the Museum für Naturkunde Berlin now shows that these small body sizes were achieved through very different growth strategies.

In an effort to open the door to new and useful products, chemistry researchers are on the continual lookout for processes that unlock important molecules and the bonds that can put them together. Such is the case for UC Santa Barbara chemistry professor Yang Yang, who builds his research around discovering novel biocatalytic methods, processes that facilitate chemical reactions with biocatalysts from evolved natural proteins.

The UNESCO World Heritage Site, which features 40,000 near-perfect hexagonal columns, formed roughly 60 million years ago during a period of intense volcanic activity
